This is a great apartment in a prime Old Town location. The flat is very comfortable and beautifully decorated, with everything you need. The location is on a quiet street in the lively and beautiful neighbourhood; walking out the front door, you are a minute or two's walk from brilliant coffee, tapas, churches, pubs, restaurants and even the Hamam.
Arturo is a great host, communication was excellent, and check-in was easy.
One thing I will say having read a few other reviews is that unless you want to stay in a modern, double-glazed hotel, there will be street noise in any Old Town apartment from pedestrians passing down the very narrow streets. If you are a light sleeper, regardless of where you stay, bring ear plugs!
