Meyling's flat is a gem. The photos are accurate and perhaps the flat is even more beautiful in person! I stayed for three nights and didn't spend much time in the flat but almost wish I did since it is so comfortable. The flat has more than enough space for one person and cozy for a couple.
The flat is located in the busy La Latina neighborhood full of cafes and restaurants, and also close to the Metro station so it is convenient as a base to explore the city (pretty easy to walk to lots of tourist attractions too).
I didn't meet Meyling but everything was handled well by Lupe, the apartment manager. The communication from Lupe was very responsive before and during my stay. She also took time to make suggestions for places I should visit and provided a handy map. I opted to check in early and there is an extra fee for that but that was communicated in the listing.
All in all I thoroughly enjoyed my short stay in Madrid and Meyling's flat was a big reason for that. I will be sure to stay again when I visit Madrid in the future.
