Hello everyone,
We had a very pleasant stay at Telmo, very well situated, within walking distance from the city center. Everything was really , really clean, we had a very good feeling about the hygiene in the apartment.
I would rate it 5 out of 5 overall, but you must know a few little details:
1) One of the bedrooms has no windows - it is the most quite one, but refreshing the air is not that easy
2) The other two bedrooms are a bit more noisy, having windows toward the street; one of them shares a wall with the place where the water meter is so you will hear the meter whenever there is water running someplace in the house.
If I will go to Porto again, I would most likely stay at Telmo again, so this should tell you that the good more than compensates for a few shortcomings.
