First, Miguel is a very friendly and helpful host. On arrival he took his time to give us his local tips which were great. In terms of the accommodation itself, I always assess my stay based on the 4 C's; convenience, cleanliness, comfort and calm(ness). In terms of CONVENIENCE Carmo is very centrally located so it's easy walking distance to everywhere. No issues. In terms of CLEANLINESS the studio was clean, tidy and bright. No issues. In terms of COMFORT, Carmo is a small studio flat so not a lot of space for furniture other than the bed but on the whole it was comfortable enough for a few days. No issues. In terms of CALM, the studio suffers greatly from the street noise. There a large windows (great) but they are not well sound insulated (not so great). The street in front of the building is a busy thoroughfare so the traffic is constant both day AND night. The streets in Porto are paved which makes the roads noisy and in addition there is a busy bus stop right outside so the noise of the idling buses is a nuisance. Being noisy is not so bad during the day (as we were out and about) but at night it was problematic. Generally my partner and I are good sleepers and even we had a few sleepless and frustrating nights owing to the constant traffic noise. It's a pity because other than this, Carmo is a great place to stay. So all in all I rate Carmo 75% satisfaction.
