The flat is really sweet and nice. Everything you need for your stay in Lissabon is there. The bathroom is quiet spacious as also the shower is. Lourenco is a very kind and helpful host. Our flight was delayed so we had to check-in about 1 hour later but that was no problem for him. Before and during the stay he immediately answered our messages when had questions. From the flat you go 5 minutes to the metro stations and supermarkets. To the city and the river Tejo you can also easily go by feet (~25 min).
The only thing I can criticize is the lock at the front door of the house. We really had problems to open it with our key. I think it's quiet old and we always needed a few minutes till we could rotate the key and open the door...
All in all it was a very nice stay at Lourencos flat :)
