This is a wonderful modern apartment in a pretty tile facaded building. The Principe Real section is the perfect place to stay as it is in walking distance to all the main sites and has great shops, restaurants and cafes but is not touristy itself. Sergio is the perfect host and the communication is great. He goes out of his way to make lots of recommendations. We were there 2 weeks. The apartment is very quiet from the street but the second week we had some noisy tenants in the rented apartment above which interfered with sleeping a bit. Everything else was excellent and I highly recommend this place. You will love Lisbon.
