The host and apartment checked off all my boxes for a great stay:
Lovely, central location. Quiet and peaceful.
Opening the building and apartment by smartphone app was easy and worked great.
The apartment was extremely clean, well-organized and perfectly suited for my friend and I. Having a second shower (in the guest bathroom) was a real treat.
Paz and Álvaro were very attentive and quickly answered all questions. There was no need to call them during the stay, however I am sure they would have been most helpful if there would have been any problems or questions.
In short - I highly recommend this host and apartment!
