Although we never met Miguel and Filipa (they were on holiday while we were there) they communicated quickly beforehand and the check-in (via electronic code) was very efficient.
The apartment is very comfortable and is furnished to a very high standard. It is easy to find in the labyrinth of small streets of the Alfama district of Lisbon (just 10-15mins from the main railway station and metro).
Staying here means you are staying in the heart of the old bit of Lisbon. There are numerous restaurants and bars nearby and the centre of Lisbon (the shopping area) is only about 30minutes walk away.
This apartment is in a perfect location for exploring both the old town and other areas of Lisbon. Recommended.
