On and off stayed for about 5 months in 2010. I found the rooms to be very comfortable and the kitchen was well equiped.
Internet functioned well, its better if you have your own CAT5 cable.
Found the staff to be very friendly bar one.
The location was ideal, a few minutes walk to the metro/Corte Ingles and less to the Praça de España bus terminal.
If you arrive by car there is free parking (on a first come first served basis).

We just returned from a 6 night stay at Real Residencia. Our room was large and comfortable, nicely appointed kitchen. Our room was on the 5th floor on the back of the building. No road noise, yes airplanes fly overhead but this was only a problem when the windows were open. The staff were extremely helpful and welcoming. The location was ideal, easy walking distance to the metro and El Corte Ingles. The breakfast was basic but to be honest with all that Lisbon has to offer starting off the day with a simple breakfast was fine. Perhaps my only complaint was there weren't many places to eat dinner nearby. Most nights we took a taxi or the metro out for dinner but it would have been nice to have a place nearby to grab a quick meal.

The suite was ideal for traveling with a child. Having kitchen facilities to store and warm up food. There was internet access if you asked for the cable at the front desk - not high speed but sufficient for our needs.

The furniture was a little long in the tooth - the couch could use new fabric and the chairs in the living room were short and uncomfortable for long periods of time. But these were minor details considering we didn't spend much time inside.

The hotel was around the corner from the metro station in a tranquil spot and just a block from a great shopping mall. Personnel very helpful. The suite was roomy. In the kitchen, a bottle of mineral water was always in the refrigerator. Very clean. Breakfast not extremely assorted but enough and good. Very good buy for your money.

Stayed here for 5 nights,payed 90 euros, for an appartement for 3 people, breakfast included, the appartment was great, clean, big, new
The location also works very good for us, because we were travelling with an infant, and there is a big shopping mall just a one block from here (wich closes around 23:30) so you can buy almost anything over there, there is also a metro station right in the corner.

Shame about internet,they didnt havent, but they offered to you to go free to another hotel to connect

Still was a very nice stay
