We spent just over a month here. Concha has made this apartment very comfortable. You can tell it has been put together with real care and attention. It had everything that we needed for a long term stay. The standard of furnishing is very high compared to a lot of AirBnBs we stay at.
The location for us was perfect, outside the main tourist track in Lisbon but close to everything you may want to visit while you are here. There are some great restaurants nearby and a well-stocked supermarket.
This is a locals neighborhood. This means you'll avoid the party crowd in the tourist center, but be aware the locals can be a bit more noisy than you might be used to. If you want to sleep with the windows open you might need earplugs!
I would highly recommend this apartment for a comfortable and authentic stay in a real Lisbon neighborhood.
