Sónia and Pedro were great hosts. Pedro was there to meet us and give us the low down on the apartment and background on the city plus an extremely useful map.
The location as mentioned in previous reviews is perfect, it's so central you can walk to most places or if not easily access the metro or tram.
The apartment itself is great, we were a party of 4 including two teenage children and it was ideal for us. We didn't really use the kitchen area much just for breakfast but it is pretty small. It is quite noisy, but then you'd expect that being right in the centre of a city. My husband likened it to staying in Soho, London.
