This 3rd floor appartment is located at a very good location for discovering Buenos Aires. It is about 8 blocks away from the metro-station Pueyrredón, which we used frequently. The kitchen is fully equipped, a supermarket only 3 blocks away. Many restaurants can be found within 3 blocks of distance including a shopping mall with food court. We used the appartment as a base for our trips to La Boca, San Telmo, Teatro Colon, Puerto Madero, Palermo Soho, Palermo Bosque and Belgrano. The host gives a lot of attention, that the department is in perfect conditions. For third day a room service is included. Here is a list of goodies: heating/cooling system works, cold/hot water, cooking with gas, refrigerator, coffee machine, hair dryer, wifi, cable-TV with DVD player (so you can watch your freshly bought DVDs), table for working/eating, cleaning accesories (in case you want to keep it clean yourself), spare towels, nice illumination, motorized jalousy (to keep out sunlight after a long night), some literature (I liked the Tango book), telephone line, hot line - if something is missing or going bad.
I personally had to get used to the noise of a town street, as I live at a very tranquil place. At around 7 o'clock in the morning the trash-collector is doing its duty in the Peña street. This worked like an alarm clock to get out of bed to discover more of BA during the rest of the day. Be aware, that the single-glazing doesn't provide a good street noise reduction.
We enjoyed staying at that place, which is also very secure. One has to pass three locked doors, in order to get to the appartment. I considered the streets of that neighbourhood to be safe as we walked day and night without meeting suspicious people.
The host is fluent in english and spanish (and perhaps some other languages) which will be an advantage for non-spanish-speaking guests. We can warmly recommend this place for a stay in Buenos Aires.
