My friend and I stayed at Javier's apartment for four nights in April 2015 and we couldn't have found a better place!

The apartment is located in the middle of the old city -- very convenient! You can walk easily to all the major sights (e.g. Mercado Central, Catedral, Plaza de la Reina, Plaza de la Virgen). There are a lot of great cafés and restaurants literally just around the corner.
The apartment itself has been newly renovated and has everything you need (a fully equipped kitchen with microwave and freezer, a design bath (fantastic shower!), enough storage space, a little balcony, a comfortable bed, linen, towels, and properly working WLAN). It is on the first floor and there is an elevator.

Javier is lovely! He gave us directions how to get into town from the airport (just a 20-minute ride by metro) and met us in person to show us the apartment. He even has guide books and brochures from the main attractions in the apartment and has a lot of great ideas where to go, what to do and which restaurants to try.
Communication with him was very easy, he speaks English fluently!

Overall, we can highly recommend this place and would certainly stay there again. Muchas gracias, Javier!
