Natalia and Roberto's place was awesome! Their assistant met us upon check in and she was super helpful and wonderful. She was also very responsive when we had questions. We stayed for 4 nights in November so it was quite cold but the heat worked fine during our stay. It is located on the third floor without an elevator so be aware if you have larger luggages with you. The space was very cozy and had everything we needed.Everything was also very clean. The kitchen was stocked with what you needed and the living room area was very comfortable. The bathroom is small but was still comfortable nevertheless. The only weird thing was we think the hot water for the shower does tend to run out especially if you flush the toilet at the same time. It wasn't a big deal since we just showered on different schedules. The bedroom area was great with very warm blankets. The window is facing the bed directly so if you're a light sleeper you might not like it since there are no black out curtains. There was also some construction going on across the street during our stay. We're city dwellers so it didn't really bother us since we're used to it. The apartment is conveniently located in the Lavapies neighborhood. The Metro stop is just a quick 5 min walk. There are plenty of shops nearby and a 24 hour grocery store just right off the Metro stop. There's also a cool market down the block that's very local. All attractions are either within walking distance or just a few Metro stops away so it was very convenient. It's a very diverse neighborhood that has plenty of signs of gentrification so as someone from Chicago we felt right at home. We would definitely stay here again if we're ever back in Madrid because of its convenience and value.
