Ana was a great host and she was very flexible with our arrival arrangements. The apartment is really lovely - more spacious than the pictures make out. It's in a fab central location, with a short walk to the local square and metro station. Ana met us at the station and took us to the apartment. She only left after she'd answered all our questions about the apartment and the surrounding area and made sure we were settled (it took us a minute to get the knack of unlocking the front door). She also organised an early taxi for us to get back to the airport which was great.
I'd definitely recommend the apartment as it is really nicely finished, well equipped and in a great location. It's so easy to see why the neighbours can spend all day peering out the windows at the world going by downstairs. There is also a lovely breeze that flows through when the windows are open. There can be a little background noise in the evenings but that's only to be expected in a city. It's just a shame that we only stayed 3 nights - next time it will be longer!
