We spent two weeks at the Kathmandu Guest House. The location is very good with a very nice garden, though you need to book the most expensive rooms to feel comfortable considering the fact that many rooms are not really well preserved and clean. Moreover during our stay we have experienced a very serious event which made us anticipate the check out (we had to stay three weeks).
On the evening of December 31 the guest house staff did not allow two of our guests to enter at the lobby. Our friends came just to greet us and when we asked for explanations the staff even called the police (the police arrived and thought that we had called them!).
It was EXTREMELY UNPLEASANT and SAD, because we had the feeling (not denied by any employee when the next day we check out) that the problem was the color of the skin of one of our guests and this is absolutely INTOLERABLE.
So unfortunately we don’t recommend this guest house to anyone who believes in certain principles… we hope all.

I stayed for two nights in Jan in KGH, as they nick name it. It is in the main street of Thamel, where you get everything at an arm's length. The hotel entry is little congested, but then it is a good hotel. The service is very good and the open house restaurant gives a good ambience. However, everytime I was asked for cash payment while ordering food in room. It was difficult convincing the management that the room and food bills should be clubbed together ann could be paid in one go at the time of check out. The hotel offers one hour free WiFI but only if you ask for it, otherwise they are ready to charge you even for that. They have a few shops too, but having located in center of main market, these may not be used by guests at all.

After traveling from India to Nepal with a tour we had one last night in Kathmandu before flying out very early in the morning. We chose KGH because we had previously spent an evening in the front bar which has a lovely atmosphere.

We made our booking online and were told we would be picked up from the domestic airport included in the price of the room. Nobody was there to pick us up and when we arrived at the hotel reception denied any knowledge of my email, even though I had an email confirmation that they would. No apology was made.

The room looked clean, although after returning from an evening out we spotted a cockroach in the bathroom. We were unable to catch it so went to bed. Sadly we found both it and another in the middle of the night, luckily we were able to catch them and remove them from the room.

The location of this hotel is fantastic, but sadly I think the hotel is trading on a good location and not good service.

We've stayed at the KGH a couple of times now. The place is always buzzing yet the rooms are quiet and the garden areas a haven from the bustle of Thamel's busy streets. In terms of location, you really can't beat it, but it does mean that you pay over the odds both in and around the hotel.

We go for standard rooms which are large and reasonably comfortable (by Nepalese standards). There's nothing particularly special about them but the beds are larger and more comfortable than some of the cheaper Kathmandu guest houses we've stayed in. The KGH also deserves at least one extra star for its showers, which are powerful and piping hot (a rarity in Thamel!)

The service can be a bit on the impersonal side, to say the least. Part of the problem is that the place always seems to be full and there are always people milling around the reception, so the staff can't always give you the attention you are entitled to expect. (But at least the reception is always manned.)

One useful service is the luggage storage, allowing you to leave your hairdryer and surfboard behind when you go off trekking. Just make sure you label your luggage very clearly and keep an eye on which storeroom it gets put in - it will make finding it amongst the thousand and one other luggage items that much easier when you get back.

We did not eat dinner there on our latest visit (the Roadhouse Café is just too tempting) but I can vouch for the breakfast here. It's not included in the room price and it's not cheap but its a cut above your average guesthouse breakfast.
