Let's start by saying that Teresa is lovely. We were welcomed very warmly but the actual stay and "sleep" was deficient.
The very first second we entered the room we were told that the heavy door was supposed to soundproof the room, "as the neighbourhood" is lively and noisy.
Soundproof is not a very accurate description.
There was music until 01.30am which you could hear and it would not let you sleep. You could hear people walking on the above floor and people going up the stairs outside your room. You could actually even hear the conversation of the people outside the apartment after the music was off.
Also, there is no door to the bathroom, which in my case I'm not very bothered about. But going to the toilet while your significant other lays in bed might not be very romantic.
Not forgetting that this is a guest house, not a private apartment, which might confuse people (as was I), thinking that this is an actual apartment.
100 euros per night is far too expensive for this.
