The pictures do not do this place justice! This apartment is huge, with a large master suite, two smaller bedrooms, two bathrooms, a room for storing sheets and hanging laundry (although we hung ours outside since the drying rack was broken -- good thing that Mar supplied clothes pins too!), a decent sized living room, a dining table that comfortably sat eight, and a balcony overlooking the street. Nearly all of the rooms had windows; although the apartment had air conditioning, we never needed to use it because the June weather was very pleasant. It did get a little cold at night and I couldn't find any blankets, but there were plenty of towels that fit the bill in a pinch. The dishwasher and washing machine were huge pluses, and the kitchen came equipped with olive oil, salt, and pepper. I loved going to sleep beneath painted images of cherubs each night. Also check out the ceiling in the lobby: there's a tiger! The apartment is near several metro stops, but we were also able to easily walk all the way to the beach one day. The neighborhood was very lively with shops and restaurants, and a large grocery store was just one block away.
When we arrived, the place was still being cleaned after the previous occupant, and it was spotless.
I also have to add - we stayed in several places during our travels through Spain and this was the only place that had really excellent, reliable hot water! The shower was a pleasure to use.
Downsides: we were two families who spoke two languages with four children between us (ages 2 to 9). When the listing states that the building carries noise, they aren't kidding. We got in trouble our first night for playing music and talking at midnight (we had to be at that volume to hear each other over the street noise, so if you're talking at night be sure to keep the windows shut). And then we got in trouble at 10:30 am when the kids were running down the hall of our apartment (they couldn't speak the same language, so they resorted to playing). After that, we tried to spend as little time as possible in the apartment since we didn't want to upset the neighbors again. So I think this gorgeous apartment would be best for grownups from the same family who just want to read in the evenings after a day of sightseeing and who leave early in the mornings.
