This apartment is beautiful and perfectly located. The space itself is quite large, and definitely the perfect size for two people. The French doors throughout were beautiful, and provided fresh air and good street noise day and night. There is even enough space on the balcony that allows you to hang out, one or two people. The bathroom is a great size, and we loved that there was actually a washing machine included (clothespin drying only!). The kitchen amenities were plentiful, and we made use of the stove quite a few times. And be prepared to get used to walking up four flights of pretty steep stairs! Overall, the place is very nice and relaxing, and it's great that a Metro stop is literally right around the corner (or a 20-minute walk to most of the central locations). It's also right next to a grocery store, which ended up being very convenient.
Our biggest issue was that the Wi-Fi was very spotty, and the last two days of our stay it didn't work at all (good thing we had an international data plan). Also, while the apartment overall seemed very clean, we did find hairs (not ours) in the sheets of one bedroom and in the bathroom that made us question how cleaned the place was before we arrived.
Also, my communication with Ester was great from beginning to end, but the rental company she is now using was another story. For one thing, they were supposed to come back with another set of keys after we checked in, but that never happened. And we were told quite clearly that check-out time was 11am, but we were quite surprised when an agent showed up at 11:08am and basically proceeded to kick us out. When I asked what the rush was (we were already packed and ready to go), she first told us that the cleaners were coming, but a few minutes later she changed the story and said that the new guests were set to arrive at any minute and needed to put their bags in the apartment. Whatever the reason, she was very rude about it and we literally felt like we got kicked out on the street.
