The flat is quite large, clean and unique. If you enjoy getting a feel for the city, then Old Town is a good place to stay. The flat is filled with unique decorations and charming touches (a pintrest lover's paradise). The beds were comfortable and we spent a lot of time at the kitchen table enjoying the sunshine. The kitchen is very well stocked.
Although there a two futons and another queen sized bed, there is only one truly private bedroom. We were three couples and two of us snore, so the split bedroom (divided by a partition) kept the others up. I do think it is a great flat for a family.
We took the train to see SPORTING play and it was easy to get to. The yellow tram runs along the streets outside the flat, so take the opportunity to get some good photos of the tram winding through the streets outside your door.
The Brick serves a Sunday bunch which is very good and it is just around the corner. Walk into the City Center and train to Sinta was only 20 minutes.
This is a very quite neighborhood and if you enjoy architecture, you will enjoy this area of town.
We did have problems with hot water in the main bathroom, but it was very hot in the smaller bathroom. Quick showers are a must in Portugal - too much to see and do.
We did have some ants in the living room (not sure if it was because of the plants), but they were no where else in the flat. This is very fixable, so it wouldn't prevent me from staying again.
Finally, we were there in January and they nights were cold. The flat does have heat and we only used it to take off the chilly rainy day we had when we arrive. I am very grateful for the heaters. We found on our travels that other places did not have heaters.
The flat it is a very comfortable and welcoming.
