Gabriel was a terrific host and he went above and beyond to help us during our stay. My husband and I both contracted Covid a few days after we arrived in Madrid (we were staying elsewhere at the time). I was very fortunate to find this lovely 2 bedroom so that we could isolate from each other. Being foreigners and not speaking the language very well, we were confused as to what our responsibilities were regarding the Covid. Gabriel found out the information for us and offered to arrange transportation to the hospital (I was that sick, even having been vaccinated) and even told me that if we needed to have someone translate to have them call him. Fortunately, the doctor spoke English pretty well and Google translate filled in the rest. Gabriel even got in touch with us the next day to see how we were feeling.
The apartment is in a lovely location! You are right above El Calamar's terrace dining which can get a bit noisy (but if you close the terrace doors you hardly hear them). There is also the Restaurant Sobrino de Botin right around the corner (we did the tour - the history and the food were both incredible). You are also very close to Plaza Mayor and San Migues Market plus dozens of other great restaurants. We didn't get to do much sightseeing this trip (I guess we'll have to come back!) but honestly just walking around in Centro is amazing. It's like walking back in time.
If I could give Gabriel and this apartment more than 5 stars, I would in a heartbeat!
