We never met Vitor personally, but the phone contact with him was easy, he always answered our messages in short time etc.

To be honest, we were a little bit disappointed with what we found. After seeing so may positive comments, we expected a nice, tidy and comfortable flat, but it let us down a little. The photos were taken after renovation, now the flat is not so "fresh" anymore. The bedroom doesn't have windows and it's not so easy to air it. The bed has squeaking springs and is uncomfortable.
The building itself is old, fusty, the staircase is very noisy, you can hear all the neighbors coming back at night, having parties etc. Also on the street, there are two buildings being renovated and the noise is insupportable. To the exclusion of the renovations, the street is rather narrow and quiet, well located if you want to be close to all Lisbon attractions. The kitchen equipment, washing machine, all the electronic things were o.k. Wifi connection very good. Bed linen, bath towels clean and the bathroom pleasant (no problem with hot water during all our stay).
However, with the price we paid for it, it was a rather unsatisfying experience. You can find better apartments for this money.
