We stay at Gemma's apartment for 2 nights and absolutely loved it. The apartment is spacious and extremely clean. The decor is tasteful and the bathroom is just gorgeous. There is plenty of storage space and the kitchen is very well-equipped. Communication with Gemma was excellent.
The apartment is located in a very quiet neighborhood about 15 minutes from the Cathedral and Plaza Espana areas. Gemma is an excellent host. Highly recommended.
