We stayed in the flat for 5 nights, 2 adults and 3 kids. First Luís was here to welcome us and help us with our hoard of luggages; very nice of him. He also gave us a couple of tips, pointed out where the shops we needed were, etc.
The flat is very well located, you can walk to many points of interest, take the (early) trams 28 or 15 (to Belem); the subway is literary 1 minute away.
The flat itself is spacious and beautiful, very well renovated and furnished; we loved the mixture of ancient with modern. The main room and main bedroom are noisy though as you get all the noises from the street and they can be late at night. But, hey, you're in the center of Lisbonne. They don't start early in the morning so you can sleep then. ☺️
The other bedroom at the back is very dark and also much quieter, we had our two eldest boys sleep in there and they were perfectly happy.
So all in all, we really enjoyed the place and would thoroughly recommend it!
Thanks Luís!
