I had a lovely stay at the City apartment. It has a prime location--only a few streets from excellent restaurants, delicious pasteis de nata, and metro/tram stops. You are also very close to the train station to go to Sintra. Maria and Rita were both very helpful, even with a VERY late check in after a delayed flight (and leaving my key inside the apartment they came to rescue me). I highly recommend a stay here to be a part of Lisbon culture and would not hesitate to stay here upon return!
