I stayed only one night at this hotel but I was very satisfied with everything. First of all, it's situated right across the keleti train station which means that there's both metro&bus stops nearby, and if you really want to walk then you'd have about 30-45 mins walk to the Vatca utca which is the center of the city. By underground, it's a 10 min ride. Also, you're close to the heroe's square. I stayed in a double room at the 6th floor. It was medium sized, comfortable bed, big wardrobe, decent bathroom with a bathtub, tv, etc. The only problem was the air-con, it was too hot, and I couldn't adjust it. The breakfast was plentiful, really good choice of sweet and more substantial food (omellete, french toast, salami,,sausages). All in all, very satisfied. Perhaps, it doesn't really look like a 4 star hotel, but I was happy with the price, location, cleanliness, food, so i guess it's a good choice.

Quite far out of the city.
Ignorant staff.
Tiny Rooms with very hard furninshings.
Poor food.

Good location. We had a twin room, which was very small (we could hardly move through it), bathroom was large. Room had a balcony. Right next to the hotel is a shopping cenar Arena. The nearest metro station Keleti, well connected with the rest of the city. Walk from the hotel to the Vaci street about 15 minutes. Next to the hotel is a great pizzeria (from the hotel, you can enter it)
Pay attention to their website, they often have some special rates for rooms, as it turns out cheaper than through other portals.

Stayed for a week and to be honest, it's good for that time.

Yes, it is far from central Budapest but you have the 24 tram going from beside the hotel which you can link up to the 2 tram to take you along the Danube to the center and see the beautiful sights. Across the road is a Metro red line which goes all over too and links up with the other metro lines and of course a main train station for trips out of Budapest. We bought a Budapest card so have just been hopping on and off all of the transport. Very handy.

Anyhow, when we checked in, the man in reception was quite distant to us for want of a better word and i found it strange to be asked to fill out details on a card such as my date of birth,city of birth etc etc. I find those details are too personal to give out just for a room. I was then asked for my credit card details which took me aback as i assumed as it all had been paid in full before hand that this would not be needed.

We were given room 218 which had a small double bed in it and the usual stuff such as a tv and fridge. The fridge is empty so you can either buy stuff from the spar across the road or ask the bar to fill it for you. The room was so small you couldn't swing a cat in it, maybe ok for a couple for a night or two but certainly not a week.
I then discovered dirt marks on the sheets and hairs too, the curtains wouldn't close completely, the walls were lined with marks and there was a suspect mark in the shower and the sink was cracked. There was also a very strong smell of sulpher/sewage. The 24 tram stop is also outside the window but that wasn't too bad.
I thought maybe i was being a tad OCD as I tend to be so i left it as we were so tired but then we were woken by doors banging and kids up and down the hall at about 5am or so which was the last straw.

I went to the lady at the reception desk and politely explained about the room and noise and she informed me that 3 groups were checking out that day hence the noise but offered us a new room. I got to check the rooms before hand and chose room 201 which faces onto the street. It is a bigger room, has no bad smell, and is nice. There are still scuff marks on the walls and the sink is cracked again but look, it's comfortable and warm and the noise from the street is tolerable as after all you are in a city!

A tip for those commenting on the dark halls, you have to hit the light switches and the halls are lit up. It is a power saving method to have the lights on a timer. Regarding the people on the streets, they are fine. We haven't been approached by anyone and I think that any big city you go to, you will have to deal with those who are homeless or down on their luck being around but it's only as a tourist you notice this.

My advice is this;
1 - if you are staying at this hotel then don't expect the type of 4**** you would get in your home country.
2 - make the most of the amazing transport on the door step.
3 - learn how to say "hello", "thank you" and "you're welcome" at least. It WILL make a difference to your time in Budapest.

I would stay here again if I return to Budapest, no question.
