We arrived before the official time, and Bielka greeted us warmly when we got to the door and she made us feel like we were old friends. Her welcome made us feel wonderful after a long trip, and was a lovely introduction to Madrid.
The neighborhood felt authentic, with older buildings and plenty of people and vehicles. Once inside, the modern small lobby was promising and the apartment was lovely. Not only was it immaculate, but everything was modern and yet decorated with character. The lightening could be soft for normal living and nice and bright when that was needed. The climate control was excellent and fast to respond. There were enough electrical outlets and WiFi was just fine for our five devices. The apartment was very cozy and very peaceful. Neighbors could not be heard. The few building noises were not intrusive and everything was quiet at night. There were two of us and my sister used the bedroom as her "domain" and I used the living room for sleeping on the sofa, which was just fine. There was plenty of storage space so we could unpack easily. There were plenty of linens and towels.
The apartment was a snug little home convenient to everything with the Legazpi Metro Station less than 5 mins from the door. Legazpi also has bus stops for many different bus lines. Madrid's transit system is superb. We had no need for a car. We also discovered the park area by the Madrid river that is close by. It is great place for walking, running, and biking.
I would recommend Bielka and Carlos' place to anyone who would like to get the feel of living in Madrid. I would love to stay there again to explore more of the neighborhood and Madrid in general.
