The guesthouse is in an awesome location. It is walking distance to the castle (recommend getting there early) and main sites as well as having a metro stop a few minutes away. We spent a lot of time in the local neighborhood eating and getting coffee in more local places and the area was fantastic. I think we may have missed out on this if staying elsewhere in the city.
The room was fantastic and came equipped with everything needed. Rafael was on hand if needed anything. There are 2 shared bathrooms, a kitchen and communal space between 4 guest rooms. Simple breakfast available - hot drinks, bread and jams - nice little addition.
We had a fantastic time in Lisbon and would also highly recommend a trip to Sintra (again the station to get there is 10 mins walk!).
I would highly recommend this apartment to stay on your travels!
