The stay was very perfect! We had an awesome city trip in arco graca and even though it wasn't very spacious, everything needed was provided. (Towels, blow dryer, even some fruits, etc.) The location is very central and you could reach everything in walking distance, there is a supermarket located at the foot of the steps, on Martim Moniz square, takes 3mins to walk there, 5mins to Martim Moniz metro station an 5mins to Rossio square.
Even though we were warned that it might get a bit louder on the streets at night, we haven't heard a thing and always slept really well.
The apartment was very tidy and cosy and the interior is very modern and everything worked perfectly. José was a very good host, we even could check-in early and he explained us everything and gave us alot of insider tips, which were really good!
There is nothing negative I could say about it, would definitely recommend it to anyone! :-)
