For two, everything was ok, but I doubt the apartment can take four. Kitchen equipped with the minimum to do some cooking. We bought everything we needed (including sugar) except Salt & pepper. Communication with the centre is readily available by bus or tram station nearby (300m). Going down to Cais do Sodre is a lovely 10min walk but a hard 15min climb up. Keep in mind that this part of Lisbon is hilly and distances you measure on a map might include stairways that may take too much effort... Quiet neighbourhood (we were unlucky with building work across the street). Comfortable bed. No heating to speak of (two electric heaters 600W each are provided. The weather was very mild when we were there and they barely provided some relief in the bedroom. Otherwise, we thought we can use the Hairdryer (yes, the Hairdryer) that was in the bathroom and was a 2200W!!!). Another thing we didn't like: with the two heaters on, using the kitchen electric cookers proved difficult - the circuit breaker kept jumping. Communication with Joana was great, she responded clrealy & almost instantly to all our queries.
