Agree with all the comments from previous reviews, both good and bad.
Very clean rooms, great to have a seperate bedroom for extended stays. Location is within easy walking distance to both the city metro and the local city rail network, a great supermarket around the corner if you want to take advantage of the fully equiped kitchen. Located in a quiet residential street and an easy, if long, walk to downtown. Apartments at the back of the building look directly into some local residential apartments, nothing inspiring. There is a constant landing of aircraft overhead, starting at 6.00am, not really a bother with the windows closed.
Be warned that the hotel does not posess an iron or ironing board, unusual for an apartment hotel, and there are no clothes washing or drying facilities.
overall a good choice and room to move around for much less than a standard 4 star hotel. We paid 100EUR with breakfast.
Recommended if only for the extra space.

just returned from lisbon, stayed at real suites...... support the positive comment regarding staff, accommodation, location etc. but i wouldn't rate it as 4* .

1. location: littered pavements & in a residential street.

2. breakfast: same every day not to mention lack of variety, we've had lot better in a 2* hotel in krakow last year.

3. lounge furniture had seen better days, lot of wear & tear

Would like to add HALAL food(pakistani/indian) is available in lisbon, we found a take away kebab place just 100yd from Rossio metro exit. they also have a resturant round the corner called TASTE OF PUNJAB, (addr. Beco dos Serradores no. 18---) food was delicious, for a hearty meal it cost €12 for 2 of us! needless to say we visited few times more.

Stayed here for three nights. Paid 100 euro per night for one bedroom apartment.
Everything was very clean, staff helpful and polite.
The breakfast was above average. We used the Praca de Espanha metro station which was very close by and also the commuter train from Sete Rios station.
The outside of the hotel was being renovated while we were staying and once the scaffolding is removed the remodeling will be complete. I would recommend this hotel to thoses who like to be in a real Lisbon neighborhood rather than in the tourist area.
We didn't notice any noise from the planes when inside the hotel.

We stayed at the Real suites for a week in june 2007 and had a fabulous stay.
The hotel itself is great. Very large apartment, has a big lounge with large flat screen TV, sofa, couple of comfy chairs, plus dining table and chairs.
There's a well equipped kitchenette with large fridge freezer (over stocked with mini-bar items on arrival), very small oven & two electric hobs. Lots of cups, plates, knives, forks etc.
The bathroom is a good size, clean and user friendly and the bedroom is an excellent size with tons of storage space.
The location is a little further away from the centre than we would have liked, about 45 minutes walk down to Rossio square, however with the Sao Sebastion Metro station less than 2 minutes away this is not really a problem.
Also it is ideally situated for a trip to the excellent Gulbenkian Museum and Park (short stroll across the road), and also a short 5 min walk to Parque Eduardo.
Breakfast at the hotel is adequate, the usual scrambled eggs, bacon etc although being veggies we stuck to the bread, cheese and cereals.
Staff at the hotel were excellent, front desk especially helpful on arrival offering maps and tips on where to go and how to get there. The cleaning / housekeeping was also superb with the room cleaned and sheets changed daily.
Nearby (above the Metro) is the huge El Corte Ingles department store, which has a good general supermarket for all your needs whilst in Lisbon.
There is a bit of noise from the planes, flying what seems worryingly close above the hotel, but we got used to this very quickly and barely noticed it as the week wore on.
All in all we had a great week and would be more than happy to return next time we plan a trip to the wonderful city of Lisbon.
