I had a fantastic time staying in Clara's apartment. The apartment was spacious and the location was perfect in the centre of the La Latina area with great restaurants and bars and the Mercado de la Cebada just across the street. The metro station was no more then 2 minutes walk. Despite it being in a very lively area the apartment itself was very quiet.
The apartment was spacious, and well equipped with everything you need for a comfortable stay.
Clara was very helpful and replied to messages very quickly- literally within 5 or so minutes. Also when I had a problem with the lock on the front door on a Friday evening Clara's sister and brother-in-law came over straight away to help.
So overall I had a brilliant stay and I completely recommend the apartment for people spending time in Madrid- the only disappointment was that Clara was away on a work trip when I was there so I didn't get to meet her!
