Filipe's place is a nice clean flat with an amazing location. Walking distance from all main attractions and tourist spots. Sizewise is percect for a couple. We stayed for a long weekend and had everything that we needed.
The only downside however is that it is not really sound isolated.
During our stay we went out sightseeing in the morning, then come back for a nap and go out for dinner in the evening. The problem was that we could hear the neighbours talking, doors from other flats opening / closing, there was even an opera singer singing from one of the other flats. So it was impossible to sleep during the day which left us tired in the evenings.
Apart from that it is an amazing place and if you don't really plan on having siestas I would definitely recomend it!
