A lovely flat, in a centrally located but quiet street, very close to convenience stores and Pez Tortilla - a great, inexpensive tapas bar popular with the locals. Multiple metro stations nearby, for quick and inexpensive travel around the city.
The flat itself was very comfortable, perfect for two friends staying (with the extra bed being a convenient bonus). The kitchen was well stocked, with salt and pepper, herbs, oils, vinegar and some fruit, as well as plenty of crockery, cutlery, pots and pans, Tupperware, etc. The fridge and freezer were reasonably sized.

Ramon and his friend were very helpful and friendly, letting us know about a local festival happening. during our stay and allowing us to store our bags in the flat past checkout.
Overall, a wonderful flat and fantastic value.
