We had a perfect time at Carlota's place.
The appartement is as described, clean, confortable and spacious. Everything is working fine and you just feel like home in a few minutes. The location is amazing, next to most point of interest of Lisbon and close by public transportation. If you want to enjoy Lisbon night life, this is great location as well, but don"t worry the appartement is quiet so you can enjoy a good night sleep :) Communication went smoothly and despite I have not met Carlota herself, she remained available by phone and helped us book taxi at the end of our stay! Good location, nice host, nice flat !
