The apartment was bright, airy, very clean and tidy, with the benefit of a terrace to enjoy the good weather.
Excellent location, being just off the Alameda de Hercules, which is a large plaza lined with many bars and cafes. As other guests have mentioned, the street can be noisy, but this is mainly the sound of car tyres, running over the cobbled street. I guess you get used to it.
The apartment is quite compact and the cooking facilities are pretty basic, so I imagine that 4 adults will find it a challenge, especially if staying for longer periods, but it is perfect for a couple for a long weekend or week stay.
Good communication from the hosts, who were responsive and dealt with a couple of queries in a timely manner and without drama.
