A Charm House is small but has all you need. The photos don't show them but there is a microwave and a TV. The beds are firm but comfortable. The living sofa is roomy and comfortable. The bathroom is small but adequate and Olga supplies the toiletries. We were there in mid-May and we never needed to cool or heat the flat. When we returned home after a day of sightseeing to the closed-up, overly warm flat, we opened the kitchen window and the small window in the bedroom and the place cooled down immediately. The flat is secure and the building is safe.
If you chose A Charm House because of it's location in Lavapies, you already know what a lively, vibrant, bar and restaurant rich neighborhood it is. Olga can give you tips on excellent restaurants a bit farther away as well. If you're not familiar with Lavapies you'll find it a multi-ethnic barrio with a mostly young population and many bars and restaurants with dining inside and outside on the busy streets. There are people on the streets day and night, walking, standing and talking and spilling out of the many bars. It's a friendly and very safe neighborhood and I never felt at risk carrying my expensive camera most places we went.
The flat is a short walk to the Lavapiés Metro station, just one stop away from Sol Metro where you can catch a train to anywhere in Madrid you might want to go. There are several grocers close by including the tiny store next door, a DIA store closer to Plaza de Lavapies and the excellent Carrefour store just south of the plaza (3 blocks away). There's also a Mercadona a bit farther away on Ronda de Atocha.
You won't hear any street noise because the building is surrounded by others and is not on the street. The people who actually live in the building full-time are quiet but there are many other units that are also Airbnb type rentals and in the 12 nights we were there, many people arrived and departed these flats. Many of them were not quiet and kept us from sleeping on 2 nights. Going outside our door and yelling “be quiet” into the courtyard several times put a stop to the noise.
