We had a great month long stay at Rui's place. Rui is an excellent, friendly host with plenty of tips etc.
The place was perfectly located for our first month in Lisbon, centrally located with easy access to just about anywhere we wanted to go. The area locally has a bunch of great restaurants too.
The apartment is bright, spacious and very well decorated. Located on a quieter street, the bedroom in particular was very quiet and dark at night, ideal for a good sleep.
All in all this is a great place to stay. We actually wanted to stay longer but it was already booked up! Maybe some other time!
